Design of Dry Chemical Fire Extinguisher Inspection Equipmentin Order to Reduceergonomic Risks for Fireextinguisher Inspectors

Abstract
It is important that a dry chemical fire extinguisher must be inspected for its readiness. For each inspection, the inspectors need to turn the fire extinguisher tank upside down to let the chemical inside the tank move and prevent solidification which would make the tank not ready for usage when needed. Each tank weighs approximately 16 kg. The inspectors have to turn each tank upside down twice (2 minutes/round). They need to put the tanks over their shoulder close to their ear in order to hear the chemical flow inside the tank, or use their hands to feel it. According to an investigation of 146 tanks and the statistical report from the first-aid room in 2019, those who visited the room for first-aid services related with skeletal or muscular injuries were mostly the security staffs from the Security Administration Department (38 out of 59 times or 64.4%). The survey and questionnaire “The Questionnaire Know Body” which includes neck, left shoulder, upper and lower right arms suggest that all 12 security staffs have the same fatigues. The current dry chemical fire extinguisher inspection affects various ergonomic health problems(Radin Umar, Ahmad, Halim, Lee, & Hamid, 2019). Rapid Entire Body Assessment (REBA)(Lee et al., 2015) is used for evaluation of posture risks so that the working postures may be redesigned or corrected. The dry chemical fire extinguisher inspection equipment has been developed to reduce ergonomic health risks for the inspectors.A REBA analysis has been performed again, and the risk score has been decreased from 13 to 3. In addition, feedbacks from the first trial of the newly developed equipment show that there are demands to increase the installation in order to reduce the ergonomic health risks(Edwards & Winkel, 2020).
